List-Id: XFS Filesystem from SGI List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Sender: xfs-bounces@oss.sgi.com Errors-To: xfs-bounces@oss.sgi.com To: xfs@oss.sgi.com Hello list ! I ran a "find dir" on one directory with 11 million files and dirs in it and it took 100 minutes. Is this a "normal" run time to be expected? I am running openSUSE 12.1, kernel 3.1.9-1.4-default. The 20 TB XFS partition is 100% full and is on an external InforTrend RAID system with 24 x 1 TB SATA HDDs on RAID 6 with one hot-spare HDD, so 21 data discs plus 2 parity discs plus 1 hot-spare disc. The case is connected through SCSI. The system was not running anything else on that discs and the load on the server was around 1 because of only this one find command running. I am asking because I am seeing very long times while removing big directory trees. I thought on kernels above 3.0 removing dirs and files had improved a lot, but I don't see that improvement. This is a backup system running dirvish, so most files in the dirs I am removing are hard links. Almost all of the files do have ACLs set. # mount | grep xfs /dev/sda1 on /backup/IFT type xfs (rw,noatime,nodiratime,attr2,delaylog,nobarrier,logbufs=3D8,logbsize=3D256k= ,sunit=3D256,swidth=3D5376,noquota,_netdev) Any thoughts?
